Silver nitrate is a non-selective, caustic, chemical which burns and contacted tissues
benefits of chemical debridement by silver nitrate
removes excess granulation tissue, removes necrotic tissue, can open up epibole, reduces
bioburden
disadvantages of chemical debridement by silver nitrate
use is controversial, painful, can stain skin, absorption of toxic silver is possible
contraindications of chemical debridement by silver nitrate
avoid use in pediatric patients as it can cause silver toxicity and is painful
bio surgical debridement
a type of non-instrumental debridement using medical grade maggots to liquify necrotic tissue
through proteolytic enzymes
disadvantages of bio surgical debridement
distasteful to most patients/caregivers, bleeding, pain, crawling sensation
contraindications or biosurgical debridement
poorly perfused wounds, exposed blood vessels, necrotic bones, limb-threatening infections
mechanical debridement by wet-to-dry dressing
a type of non-instrumental debridement done by using damp gauze in the wound bed that is allowed
to dry out to trap tissue which is then pulled off during dressing changes
benefits of mechanical debridement by wet-to-dry dressing
cheap, dressing change is easy to perform, use in heavily necrotic or infected wounds without
granulation tissue
disadvantages of mechanical debridement by wet-to-dry dressing
painful, non-selective (will pull off healing tissue with necrotic tissue), time consuming (multiple
dressing changes daily for weeks)
contraindications of mechanical debridement by wet-to-dry dressing
clean granulation wounds
mechanical debridement by irrigation/pulsatile lavage
a type of non-instrumental debridement using fluid and pressure to remove surface debris and
bacteria form the wound base without damaging healthy tissue
, Page 2 of 21
benefits of mechanical debridement by irrigation/pulsatile lavage
wound cleansing
disadvantages of mechanical debridement by irrigation/pulsatile lavage
potential for splash contamination - wear PPE!
goal PSI for pulsatile lavage
4-15 psi
mechanical debridement by ultrasonic mist
a type of non-instrumental debridement using low-frequency ultrasonic device to produce acoustic
energy that has mechanical and thermal effects which degrade fibrin and remove biofilm
benefits of mechanical debridement by ultrasonic mist
painless, wound cleansing, biofilm reduction, stimulates cells to accelerate the healing process
disadvantages of mechanical debridement by ultrasonic mist
costly, time consuming, inconclusive research
conservative sharp wound debridement
a type of instrumental debridement using sharp instruments to remove frank, devitalized tissue
without causing bleeding
surgical sharp debridement
a type of instrumental debridement using a surgical instrument to aggressively remove necrotic
(and sometimes non-necrotic to open up wound edges) tissue, causes bleeding
TIMERS
Tissue management
Inflammation/infection control
Moisture balance
Edge/epithelial advancement
, Page 3 of 21
Regeneration/repair of tissue
Social/patient related factors
Framework used to provide an optimal physiologic wound environment that is conducive to
healing
TIMERS
Goal of tissue management
to remove non-viable, necrotic tissue as well as non-functional tissue such as hypergranulation
goal of inflammation or infection control
eliminate infection and control bioburden
goal of moisture balance
not too wet and not too dry
provide moist wound therapy, absorb excess drainage, control odor, fill dead space, control
swelling, protect periwound
goal of epithelial/edge advancement
keep wound edged open, address epibole and undermining, remove callous, protect periwound
skin
goal of regeneration/repair of tissue
cellular products, tissue based products, advanced therapies such as hyperbaric treatment of NPWT
goal of social/patient related factors
develop a patient-centers POC, patient engagement, holistic assessment
why use debridement?
to remove necrotic tissue or debris, remove and reduce biofilm, remove infected tissues, in
palliative care to control odor, to facilitate wound visualization, in chronic wounds to convert to
acute wound to promote healing
autolytic debridement
a type of non-instrumental debridement that uses the body's own WBCs, enzymes, and moisture
to re-hydrate, soften, and liquify hard eschar and slough
benefits of autolytic debridement
